To all whom it may concern:

Be it known that 1, Homes H. TAYLOR, a citizen of the United States,residing in the city of Oakland, county of Alameda and State ofCalifornia, have invented a new and useful Improvement in ResilientWheels; and I do hereby declare the following to be a full, clear,concise, and exact description of the same. 7

This application is filed in accordance with the decision of the FirstAssistant Commissioner of Patents in ex parte Horace H. Taylor andLeonard A. Moberry declaring invalid the joint application of Horace H.Taylor and Leonard A. Moberry, for resilient wheels, filed July 2 1,1916, Serial No. 110,921.

This application. is filed as a substitute for and as a continuance ofsaid joint application of Horace H. Taylor and Leonard A. Moberry andsaid joint application of Horace H. Taylor and Leonard A. Moberry ishereby abandoned.

My invention is an improved resilient wheel operable without pneumatictires.

More particularly my invention includes a plurality of cylinders mountedon the wheel and acting upon a fluid in such man ner as to maintain therim resilient with relation to the hub of the wheel.

In this specification and the annexed drawing I illustrate my inventionin the form which I consider the best, but it do not limit the inventionto such form as it following the description herein I intend to coverthe invention in whatever form it may be embodied.

Referring to the annexed drawing which forms part of this specificationand the following claims:

Figure 1 is a section of the inner portion of my improved wheel takentransversely of its axis. 7

Fig. 2 is a section of the inner portion of the wheel taken on its axis.

Fig. 3 is a perspective view of one of the piston valve members.

In the drawing 1 indicates an inner hub adapted to rotate around an axle(not shown) and 2an outer hub surrounding the inner hub; The inner hubis'formed with a rear annular flange 3 and an external thread i is cutinthe periphery of. the front end of said hub on which thread screws a nut5. Internal rear and front annular flanges 6 and 7 are formed in theouter hub 2 which flanges fit between the hub flange 3 and the nut 5 insliding engagement therewith, whereby the outer hub is maintainedagainst axial displacement on the hub 1 and allowed to floattransversely with relation to the axis of the inner hub. In the idealrelation of the two hubs their axes are coincident. A cap 8 screws onthe thread a on the front end of the inner hub against the nut 5 andcloses the front end of the inner hub and forms a lock nut preventingthe nut 5 from working off the front end 01 the inner hub. The outer hub2 is formed with a plurality of cylinders 10 extending radially from thecenter of thehub within which cylinders are reciprocatively mountedplunger-cylinders 11. On the heads at the inner ends of the plungercylinders 11 are cams 12 for engaging a sleeve 13 surrounding the innerhub 1. The sleeve 13 is formed with an annular flange 1 1 which engagesa Hat side of the cams 12 and prevents axial turning of the plungercylinders 11. Caps 15 screw on the outer ends of the hub cylinders, onwhich caps are formed inwardly extending hollow pistons 16 which extendinto and are adapted to reciprocate in the plunger cylinders 11. Thepistons 16 being of less diameter than the cylinders 6 provide annularspaces 18 between them and the cylinders 6 in which spaces springsl? arecoiled around the pistons, the ends oi which springs bear respectivelyagainst the caps 15 and the outer ends of the plunger cylinders 11 andmaintain the plungencylinders 11 at the limit of their innermostposition with the cams 12 in engagement with the sleeve 13. The innerend of the hollow pistons 16 are closed by heads 19 which screw intosaid end of the piston. Valves 20 control communication between theplunger-cylinders 11 and the interior of pistons 16. Said valves eachinclude a valve member 21 extending through and securely fitted withineach piston head and a threaded valve controlling member 22, the stem ofwhich is threaded and extends through and engages with, a threadedopening in. each of the hub cylinder caps 15. Each valve member 21 has aport 23 extending 'therethrough and is formed with a conical seat 2% toreceive conical head 25 on the inner extremity of the valve controllingmember for closing the valves and shutting off communication between theinterior of cylinders 11 and pistons 16. The outer end of the 'alvecontrolling members 22 have thumb wheels 25 fixed thereon, whereby saidmembers are turned, and moved axially by their threaded engagement withthe cup openings, for opening and closing the valves 20. Lock nuts 26screw on the threaded valve stems against the outer faces of the hubcylinder "caps and lock the valves 20 open the desired degree. Thecylinders 11 and hollow -p'ist'ons 16 are suitably charged with anysuitable fluld as for example 011.

Packing rings 30 are provided on the exterior of the plunger cylinders11 in engagement with the interior of the outer hub cylinders 6 forpreventing any oil from leaking past the plunger-cylinders into theinterior of the hub.

Air inlet valves are provided in the hub-cylinder heads 15 for theadmission of lows The pressure of the piston heads 19 on the oil in thecylinders 11 normally balances the outer hub and rim so that their axescoincides with the axis of the inner hub.

The valves 20 being properly adjusted to regulate the flow of liquidthrough their ports 23, as the wheel rotates over an uneven surface theshocks on the rim of the wheel are transmitted to the outer hub 2through the spokes 41, which causes the lower pistons 16 to moveinwardly within the lower cylinders 11, and force oil through the valveports 23 from said cylinders 11 into said pistons 16 and thereby absorbthe shocks on the wheel'rim before reaching the inner hub 1,

thus relieving the inner hub of such shocks.

As said lower istons andcylinders rotate above the axis of the wheel andthe succeeding pistons and cylinders take their-position below the axis,the hub 2 and wheel rim are restored to axial alinement withthe hub 1 bythe resistance of the liquid in the approaching succeeding cylinders,while the preceding pistons above the axis are forced outward and theoil flows therefrom through the openings '23 back into the cylinders 11above the axis, filling said cylinders so that the preceding cylindersand pistons will sustain the wheel. rim and its hub 2 in axial alinementwith the hub 1 when said cylinders and pistons agam rotate below theaxis of the wheel.
